A: No. OTP Smart Fill exclusively monitors your Gmail inbox for email-based OTPs. It does not intercept phone SMS messages.

Currently supports one account at a time. Q: Is this safe to use with my work Google account? A: Yes. The extension only requests read-only Gmail access via your organization's standard Q: What happens if I have multiple tabs open? A: The OTP is auto-filled only into your currently active tab. All other tabs receive a clickable notification that lets you manually trigger the fill. Q: Does it slow down my browser? A: No. The polling logic runs in a background service worker with optimized, non-blocking DOM search. It has zero impact on page rendering or JavaScript execution. • storage — Saves your OTP history and monitoring state locally • tabs — Identifies the active tab to target auto-fill correctly • identity — Manages your Google OAuth2 token securely via Chrome • notifications — Shows desktop alerts when a new OTP is detected • alarms — Keeps the background Gmail check running reliably • host_permissions (googleapis.com) — Required to call the Gmail API Experiencing an issue?
